DESCRIPTION
The problem is a 33% passable fish passage barrier culvert under Newskah Road on an unnamed tributary to Newskah Creek south of Aberdeen in the South Bay Subbasin. The degraded watershed process this project addresses is fish migration access to upstream spawning and rearing habitat. The solution is to design and permit a project to remove the barrier culvert and replace it with a structure that is passable to all species and life stages of salmonids and other aquatic species in the tributary. Project components include completing topographical survey, engineering, design drawings and permitting for the barrier site. The resulting materials will be used to apply for future grants for project construction.
The problem is a 0% passable fish passage barrier culvert under Newskah Road at road mile 3.4 on an unnamed tributary to Newskah Creek south of Aberdeen in the South Bay Subbasin. The degraded watershed processes this project addresses is fish migration access to upstream spawning and rearing habitat and floodplain connectivity. The solution was to design and permit a project to remove the barrier culvert and replace it with a structure that is passable to all species and life stages of salmonids and other aquatic species in the tributary. Coho salmon, steelhead and cutthroat trout are expected to use the stream once passage is provided. Project components included evaluating correction alternatives, identifying a preferred alternative, estimating cost, and completing design drawings and permitting for the barrier correction. The resulting materials will be used to apply for future grants for project construction. As of May, 2021 all the permitting, designs and cost estimate have been completed making the project ready to implement once construction grant funds are obtained.
